Alternatively, computer program implemented steps or acts may be combined with operator or human implemented steps or acts in order to carry out an embodiment of the invention.

Embodiments according to the present invention allow users to perform offline three-dimensional (3D) virtual world activities and then, deploy or synchronize the results to those activities within the live 3D virtual world. Therefore, 3D virtual world content may be generated offline and then uploaded to the live 3D virtual world. According to embodiments of the present invention, a part of a virtual world may be captured and stored offline. The captured virtual world content may then be run on a processing device, which is disconnected from the live 3D virtual world, allowing the same experience for a user as would be available in the live or online 3D virtual world, as well as, the ability to generate new 3D virtual world content. The captured snapshot of a particular region or portion of the live 3D virtual world may be stored on the disconnected processing device and have full functionality with virtual world server capabilities.

A user may be allowed to explore a particular section or portion of the virtual world by a local virtual world module or other means and to make offline changes to the virtual world portion while not being connected, however, when the user (controlling an avatar in the virtual world) returns to an online connection, they may replicate any changes that the user was permitted to make within the offline virtual world portion and synch this content up with the live or online virtual world. Changes may include objects created, objects modified, new content, etc. The offline capabilities may also provide better performance at build time for complex components by removing network bandwidth constraints. The processing device may be any type of processing device such as for example, a personal computer, a server, a workstation, etc. The local virtual world module may be downloaded from a server hosting the virtual world environment in association with capturing and downloading the snapshot of the particular region or portion of the live 3D virtual world. In another embodiment of the present invention, the local virtual world module may be obtained from a vendor or third party and preloaded on the processing device.

According to embodiments of the present invention, as noted previously, a section of a live virtual world may be downloaded to a processing device such as a personal computer. The processing device is then disconnected from the live 3D virtual world. Any changes that are allowed to be made by a user in the downloaded section of the virtual world may be uploaded and synchronized back to the live 3D virtual world environment once a live connection is reestablished. For example, a user may crop a section of the virtual world for offline use by drawing a square on a map. Before downloading this portion of the map, the processing device may determine, or an application running on the processing device, such a local virtual world module or other means, may permit determining if there is enough storage available for storing the cropped section of the virtual world and alert the user accordingly. A user may also crop multiple sections of the virtual world. This may be accomplished via a “rubber band” mechanism that may give the user the ability to grab an object in 3D. In addition, according to embodiments of the present invention, once the section of the 3D virtual world system has been cropped, the user may be offered the option of placing a “block” on that section of the live virtual world, thus preventing any other user from making changes to that section of the virtual world. Multiple users may download and use portions of the virtual world but may not be able to change content in the downloaded portion if the portion of the live 3D virtual world content has been blocked. If the “cropped” section of the virtual world is not “blocked”, then a policy of “last change wins” may take effect when changes are uploaded to the live 3D virtual world and synchronized.

A user may have a preinstalled local virtual world rendering engine on the user's processing device allowing recreation of selected virtual world content. Attributes and data elements of the live 3D virtual world may be downloaded into the local virtual world rendering engine. The user may then be free to experience the downloaded section of the virtual world while offline and may be allowed to create objects and other portions of virtual world content in the offline section of the virtual world by the virtual world rendering engine. For any changes made to the offline section of the virtual world offline (e.g., creating new objects, etc.), data that describes these changes may be stored in a separate storage location from where the downloaded virtual world is stored. After reconnection back to the live or online 3D virtual world, a user may then be permitted by the virtual world environment to synchronize any changes made in the offline virtual world content. Any new virtual objects that were created may be updated in the live 3D virtual world. Further, at the same time, objects created in the live 3D virtual world while the user was offline, may be updated in the user's offline section of the virtual world (if that portion of the live 3D virtual world was not blocked).

Moreover, according to embodiments of the present invention, a user may be allowed by the rendering engine, local virtual world module or other means to create virtual world objects and content outside of the virtual world (e.g., objects and content that does not currently exist in the online or live 3D virtual world) without having downloaded any content from the live 3D virtual world. Once created, the user may connect to the live 3D virtual world content and deploy the newly created virtual world objects and content. The created virtual world objects and content may be deployed to a specific section/location (e.g., xyz coordinate) of the live 3D virtual world.

FIG. 1 shows a diagram of system for generation and synchronization of offline three-dimensional (3D) virtual world content according to an example embodiment of the present invention. The system 100 may include a server 101 and one or more workstations 102 where the server 101 and the one or more workstations 102 may be interconnected to a network 103. Although one server 101 is shown, there may be multiple servers connected to the network 103 and accessible by the one or more workstations 102. The server 101 may host the virtual environment 105 and also contain a controller 104 and storage 106. Therefore, a user at a workstation 102 may access the virtual environment 105 hosted on the server 101 and control an avatar in the virtual environment 105 to select a portion of 3D virtual world content from online or live 3D virtual world content. The user may then store offline the selected portion of 3D virtual world content taken from live 3D virtual world content. The user may access the offline 3D virtual world content and experience the portion of 3D virtual world offline, and may generate new virtual world content. Changes in the offline 3D virtual world content that occurred while accessing the offline 3D virtual world content may then be uploaded to the live 3D virtual world and synchronized with the live 3D virtual world content.

FIG. 2 shows a flowchart of a process for generation and synchronization of offline three-dimensional (3D) virtual world content according to an example embodiment of the present invention. In the process 200, in block 201, live 3D virtual world may be accessed. In block 202, a portion of the live 3D virtual world content may be selected or cropped. In block 203, the selected/cropped portion of the 3D virtual world content may be stored offline. In block 204, the offline 3D virtual world content may be accessed and in block 205, any changes to the offline 3D virtual world content may be stored. In block 206, the live 3D virtual world may be re-accessed and in block 207, the changes in the offline 3D virtual world content may be uploaded to the live 3D virtual world and synchronized with the live 3D virtual world content.

FIG. 3 shows a diagram of a system for generation and synchronization of offline 3D virtual world content according to another example embodiment of the present invention. The system 300 may include a 3D virtual world system 301 and a processing device 302. The 3D virtual world system 301 may be hosted on a server (not shown). The processing device 302 may connect to the 3D virtual world system and a user may select a section 203 of the 3D virtual world system 301 and may download 305 and store the downloaded section 303 on a storage device 304 on the processing device 302. The processing device 302 may then be disconnected from the server hosting the live 3D virtual world system 301. A rendering engine 306 or other local or remote virtual world module operable on the processing device 302 renders the virtual world section 303 of the 3D virtual world system allowing a user to access the section 303 and experience offline the downloaded section 303 of virtual world, also make changes or add new content to the downloaded section 303 of virtual world. Any new virtual world content 307 created by the user may be stored in the same storage device 304 or a separate storage device 308. In this example embodiment, the newly created objects and virtual world content 307 is stored in a separate storage device 308. The processing device 302 may reconnect to the 3D virtual world system 301 and upload 308 the newly created virtual world content 307 where it may be synchronized with the existing live 3D virtual world content in the 3D virtual world system 301. Although the storage device containing the downloaded virtual world content 303 and the separate storage device 308 containing new virtual world content 307 are shown as existing in the processing device 302, these storage devices may exist outside of the processing device 302.

FIG. 4 shows a flowchart of a process for generation and deployment of offline 3D virtual world content according to an example embodiment of the present invention. In the process 400, in block 401, 3D virtual world content may be created offline. In block 402, the live 3D virtual world may be accessed. In block 403, a specific section of the live 3D virtual world content may be identified for deployment of the created 3D virtual world content. In block 404, the created 3D virtual world content may be deployed into the specific section of the live 3D virtual world.

FIG. 5 shows a system for generation and deployment of offline 3D virtual content according to an example embodiment of the present invention. The system 500 may include a 3D virtual world system 501 and a processing device 502. A user may use a rendering engine 503 at the processing device 502 to generate and create new 3D virtual world content 504. The processing device 502 may then be connected to the 3D virtual world system where the newly created content 504 may be uploaded 505 to the 3D virtual world and deployed. The newly created content 504 may be deployed at a specific section of the 3D virtual world system 501.
